  • Patent number: 9688705
    Abstract: Embodiments describe methods of synthesizing metal mesoporphyrin compounds. In embodiments, a metal mesoporphyrin compound may be formed by hemin transmetallation and subsequent hydrogenation of the tin protoporphyrin IX to form a metal mesoporphyrin. In other embodiments, a method of synthesizing a metal mesoporphyrin compound comprises forming a protoporphyrin methyl ester from hemin and converting the protoporphyrin methyl ester intermediate to a metal mesoporphyrin compound through metal insertion and hydrogenation. In other embodiments, a metal mesoporphyrin compound may be formed from hemin by a hydrogen-free hydrogenation method to form a mesoporphyrin IX intermediate followed by metal insertion and hydrogenation. In embodiments, a method of synthesizing a metal mesoporphyrin compound comprises forming a mesoporphyrin IX dihydrochloride intermediate compound and converting the mesoporphyrin IX intermediate to a metal mesoporphyrin compound through metal insertion.

  • Publication number: 20130158362
    Abstract: Some embodiments relate to methods of treating hyperbilirubinemia comprising administrating a therapeutic amount of a metalloporphyrin to an infant. Administration may occur when the infant's measured total serum bilirubin levels are at or below about the level suggested by the AAP nomogram for initiating phototherapy, when the infant's measured total serum bilirubin levels are at about the level suggested for initiating phototherapy in an infant, or when the infant's measured total serum bilirubin levels are at about the level suggested for initiating phototherapy. Administration may occur without regard to the total serum bilirubin level of the infant. In some embodiments, administration of the metalloporphyrin does not cause QT prolongation.
